To (ZZZ whom it may concern.

Be it known that I, "Wnmnuu L. AUSTIN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Car which the following is a specification.

, The object of my invention is to construct a car truck in such a manner as to decrease the space between the wheels. making a truck with a very narrow wheel and dccreasing the width of the transon'ls and the mechanism mounted thereon by usinga single linlr suspended at each side instead 01 a double link as heretofore.

- The invention also relates to the equalisstrength to the structure;

stance. mg beams so arranged as to give greater the equalizing beams concealing and protecting the springs.

lV iile my invention is particularly adapt- 1 ed for use as an electric truck, it will be un derstood. that it can be used for other purposes Without departing from the essential features of my invention.

In the accompanying drawings: ignre I d blocks; a.

Extending from one frame B to the other is a bar B forming the lower member of the truck side frame; the bars A forming the upper member. Extending; at one end of the truck is a rigid frame D consisting of a lower member d and an inclined member d; one secured at the lower end of the box frame 3 and the other secured at the'upper end thereof. The frames D, it). one at Teach side, are connected by the beam forming a guard D. Pivoted at d at the opposite end of the cruel: is a frame?? 0011-" These of the main frame of the truclr tion.

Resting upon the boxes Z), 6 on each side are a pair of These beams exthe other and have project. beyond the wheel base truck and from these ends are suslat equalizing beams E. tend from one box to ends 0 which of the pended the bars 6' supporting the free ends of the electric motors in the present. in- S 'nings c are used to make a yielding connection between the extensions and the bars. Other forms of suspension may be used withoutdcpartine' from my inven- The bear. s are recessed at c at; the center so as to allow the transoms u, a to extend into the side frames and the e add considerable strcn th t the structure.

lllountcd between the. transoms at each blocks are supported by the upper sntion' of the double ellipti -al spring l mounted on each side of the truck'between the two equalizing beams of the springs resting securely bolted to both upon a plate 13 equalizingbcams, as illustrated in Figs. 3

W 1 and o. 'ihcse springs are arranged lOllgltudinally'in respect to the truck and are confined between the two equalizing beams, loy angement the springs are completely out of the Way of any other mechanism of the truck and are protected by the heavy equalizing beams.

7 are spring seat plates pivotally mounted on transverse bolts 6 p ssing throu h both etuahzin beams ill and mounted between these spring plates f and the under side of the side bar A are coiled springs F, thus the frame of the truck is connected to the equalizing beams which are supported by the box by a double elliptical spring at-each side and two coiled springs, all mounted between the equalizing seams. This construction gives additional room for the brake mechanism and for the motors and other connections.

.Clhe equalizing beams on one side of the truck are connected with those on the other side or the track bars E one situated oneach side of the transom and these bars are utilized to suspend a brake shoe described.

hereafter.

In order to allow the equalizing beams E, E to extend down suil'iciently to retain or to support the double elliptical spring F, l

rovide the bar B forming the lower mom or of the truck frame so that the bod portion of the bar will extend bach of the equalizing beams; the ends bearing; against the box frames l3 and bolted thereto 'lhus while I obtain a rigid connection at the lower end of the truck frame I provide ainple room for the equalizing beams and the double elliptical spring supported thereby.

Mounted between the two transoms it is a bolster I shaped as clearly shown in Fig. 5, havingacenter bearing plate I", side bearing plates '1, and these side bearing plates carry shoes '3 bolted to the side bearmg plates and spacing plates are "used so that the bearing plates can be adjusted. at different heights, as desired. Thev bolster is made in a single piece in the present instance in the manner shown in Figs. 5 and 8, being solid at each end and at the center and-having slots 1" for the reception of the links G on each side of the center, as shown in Fig. 5. These links are mounted on pins H adapted .t'o rest on the transom A, as shown in Fig 6, and are confined thereto by boxes a the pins being cut away at h, h, as shown. in Fig. '2', for1ning a flat surface which rests upon the transoms A,'A holding them in position and the ends h overlap the edges of the transoms to J-re ent longitudinal movement of the bar.

he upper portion of the link (3- throu h which the pin H passes is illastrated in Fig. 6 and extends the full width of the space between the transoms, being reduced at, the lower end so as to pass into the slot '5 in the bolster I. A pin J extends through the opening in the bolster and through an openi in the link and is held in place. by the s transoms A, A; I

a will now describe the brake mechanism and the method of hanging it from my lill proved trunk, but the method itself forms no part of the present invention.

The brake shoes N, N are hung by links n, n from l -shaped hangers a secured to the cross bars E which are attached to the equalizing beams E, E at each side of the truck. The shoes are actuated by the levers m, m CO'fll'leCltHll to the brake beams "in? and connected together by the rod-m. The lcver m is hung to the frame and the lever m is actuatedby the Ye operating mechanism. The brake, p." l without. departing turcs of my invention,

space is allowed for the accommodation of the brake mechanism; the center portion of truck being entirely free of mechanism so as to allow tor the accommodation of the motor and its mechanism. The bolster is made very narrow and suspended from the transoms by a single link at each side of the center, making a construction especially applicable for an electric motor truck in which the motors are carried by axles and suspended at each end of the truck.
